I remember there was a Hollywood movie that said at the beginning that during the Civil War, a battleship carried a shipload of treasure to Africa. The main content is for modern people to explore.

National Treasure Ben Franklin Gates (played by Nicolas Cage) is an adventurer who loves archeology. Since he was a child, Ben's grandfather, John Adams Gates (played by Christopher Plummer), told him a shocking secret. In order to strive for independence and establish a country, the United States launched an independent war with Britain. After the victory of the war, the United States was able to successfully establish a country. At that time, the United States originally had a batch of treasures used as war reserve funds, which were buried in a certain place by the three founding fathers of the United States, George Washington, Thomas Jefferson, and Benjamin Franklin. So far, no one knows where this lost national treasure is, and the secret of where the treasure is buried is hidden in the dollar sign and the Declaration of Independence, which created the democratic system of modern human society...

In fact, Ben’s father also knew about the treasure. He believed that the Gates family was too deeply involved in this secret.
